Suomi NPP CrIS Level 1B Full Spectral Resolution V1 (SNPPCrISL1BFSR) at GES DISC

Version 1 eng
  • Abstract
    The Cross-track Infrared Sounder (CrIS) Level 1B Full Spectral Resolution (FSR) data files contain radiance measurements along with ancillary spacecraft, instrument, and geolocation data of the CrIS instrument on the Suomi National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (SNPP). In December 2014, the CrIS instrument on the SNPP satellite doubled the spectral resolution of shortwave infrared data being transmitted to the ground. In November 2015, additional points were included at the ends of the longwave and shortwave interferograms to improve the quality of the calibration. Prior to November 2, 2015 the data are only available in Normal Spectral Resolution (NSR), after November 2, 2015 at 16:06 UTC, the data are available in both NSR and Full Spectral Resolution. The FSR files have 2,223 channels: 637 shortwave channels from 3.9 to 4.7 microns (2555 to 2150 cm-1), 869 midwave channels from 5.7 to 8.05 microns (1752.5 to 1242.5 cm-1), and 717 longwave channels from 9.1 to 15.41 microns (1096.25 to 648.75 cm-1). Each CrIS field-of-regard (FOR) contains 9 field-of-views (FOVs) arranged in a 3X3 array. The Level 1B files contain 30 FORs in the cross track direction and 45 in the along track direction. Data products are constructed on six minute boundaries.
  • Purpose
    The radiance data are used for sounding observations needed to retrieve profiles of atmospheric temperature, moisture, and trace gases for civilian operational weather forecasting as well as continuity of these measurements for climate monitoring purposes.

    Quality
    This is a beta version of the CrIS Level 1B Full Spectral Resolution product that is being provided in order to familiarize users with the CrIS L1B FSR data format, provide L1B FSR data for the Level 2 science teams to work with as they develop their own software, provide L1B FSR data for use in preparing proposals, and solicit feedback from users on both data format and contents.
